A very capable full frame camera with lots of resolution. Well balance with 300mm f:4 L lens fitted on it.

Cons:

Poor QC fresh out from the factory. Mine gives out an error 20 after my 2nd outting into the forest. Canon have one of the circuit board replaced after I sent it back to them on the second time. The 5D Mk2 is a pricy piece of equipment and these QC issue should not happened on the 5D Mk2. Now, I keeping my finger cross that this won't appear again.

I used it mainly for landscape, macro and portrait photography so I don't really know the slight difference in attaining focusing.

Resonably solid body (inside electronic still questionable)
Very good ISO speed and soft shutter release.
It's a great full frame camera for jungle trekking due to its light weight body. The 21mp sensor has enough resolution for most prints sizes. It would be great if it has a pop out flash built-in and a wireless flash control trigger built into the body rather then mounting an ST-E2 to go wireless.

Canon should really relook into their quality control issue as I have some photographer friends also complaining about Canon quality control of late; if Canon wants to remain in the front line of the professional camera equipment sales.

Very sharp and ease to use if you have been a Canon EOS user. Very well balance in the hand and light for a full frame body.

Cons:

Canon quality (QC) is on a decline. Mine show up Error 20 after taking it out on my 2nd trip to the outdoor in the forest. Send back to Canon twice before they change one of the circuit board. For a pricy camera like the 5D Mk2, I don't expect these to happen but it has happened as the previous person has reviewed. Canon must wake up before more damage to their reputation is done.

As mentioned, it a fine piece of equipment with exceptional resolution and reasonably price for a full frame. It's light and solidly built and I use to mount it on my tripod while I trek, not too heavy on my shoulder.
With a Canon 300mm f.4L mounted, it is still very well balance on my hand.

Canon should look into thier quality control like this pricy 5D Mk2. I have read many report and complain on the 5D Mk2 from friends and photographers on Error failure.

Will I recommend to photographer? yes, provided Canon improve on their QC.
